Hi Support, I am sorry I have another strange issue. It looks like Chilkat crypt class is dependent on Microsoft.SqlServer.Types.dll.

Actually I put my simple application based on one c# 4.5 form on a brand new installed machine based on Windows 7 Home Premium 32 bit and it did not run properly.

The confusing thing was that the app was working on development machine with chilkat component but not on the test machine. So it means there must be something on development machine which was missing on the newly build machine (Windows 7 32 bit Home Premium), after spending hours of investigation I found that this Microsoft.SqlServer.Types.dll was missing in C:Program FilesMicrosoft SQL Server110sdkassemblies.
The purpose of this message to get confirmation from you guys that chilkat.dll is dependent on some of microsoft dlls so that i can document for our reference.

The Chilkat ActiveX DLL's have no external dependencies. (Except for the case if, for example, a ChilkatCert object is used, then you would need the ChilkatCert.dll. In other words, your app would need the DLL for whatever objects it may use.)
